ext4: Simplify flags in ext4_map_query_blocks()

Now that we have EXT4_EX_QUERY_FILTER mask, let's use that to simplify
the filtering of flags for passing to ext4_ext_map_blocks() in
ext4_map_query_blocks() function. This allows us to kill the query_flags
local variable which is not needed anymore.
